SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented July 31, 1917.

Ta all whom it may concern:

Be it known that we, ROBERT L. WARNER, of Concord, in the county ofMiddlesex and State of Massachusetts, and GEORGE F. DAY, of Needham, inthe county of Norfolk and said State, have invented a new and usefulSight for Firearms, of which the following is a specification.

Our invention relates to that type of sight in which a rotary member hasoperative portions at different distances from its axis to cause changesin elevation of the sight member.

One feature of our invention is such a rotary member combined with anintermediate member to move the member carrying the sight.

Another feature is the mounting of the rotary member on the base for thesight member.

Another feature is the location of the rotary member at that end of thesight member which is toward the user.

Other features will be pointed out below.

In the drawings:

Figure 1 is a plan of a sight embodying our invention;

Fig. 2 is an elevation thereof;

Fig. 3 is an enlarged diagrammatic view, the rotary notched member beingin section on line 33 of Fig. 4; and

Fig. 4 is a detail plan showing the rotary notched member.

, Upon the firearm A is mounted base B having worm b to cooperate withgear I) so as to shift the base on the pivot 12 to allow for windage.Upon the base is mount ed shaft 5 which is the pivot for frame Dcarrying sliding sight D, this frame and sliding sight being familiar tothose skilled in this art. A novel feature, however, consists inproviding a sighting portion d which is an open sighting notch in theform shown.

Mounted on shaft 6 is rotary member E the shaft being suitably upset atits ends to hold the frame and rotary member E against undesired axialmovement but permitting relative rotary movement between them.

The rotary member E is provided with a plurality of grooves or notchese, 6, e 6 and 6*, the inner portions of the grogves being atprogressively increasing distances from the axis of the rotary member E,the inner portion of groove e being nearest said axis and the innerportion of groove 6 being farthest from said axis.

Pivoted to the base B at f is rocking lever F having a nose 7 at one endto engage said grooves and having an inturned nose f at the other end toengage the under side of frame D. A slot f on lever F cooperates withpin 7 on the base to limit the movement of said lever. When the partsare in the position shown in Figs. 2 and 3 the sight opening d is in itslowest position, such as might be used if the object were one hundredyards away, the number 1 being conveniently discernible to the user ontop of the rotary member E. Rotation of member E in the direction of thearrow in Fig. 3 will bring groove 6 into engagement with nose f and soon with the other grooves by further rotation of member E. This willresult in gradually lowering nose and gradually raising nose f whichconsequently raises frame D and therefore the sighting portion (Z asindicated by the several dotted line positions in Fig. 3.

Rotation of member E is limited in one direction by shoulder 6 nose fthen engaging groove e, and in the other direction by shoulder c, nose fthen engaging groove 6*.

Nose f is held in engagement with the desired groove by reason of thefact that the frame D presses downwardly on nose f this pressure beingdue to the flat spring G which bears against frame D at the left of itspivot in the manner well known in this art, this spring acting as iswell known to hold said frame elevated as is shown in dotted lines inFig. 2 in case it were desired to use the sliding sight D for targetwork for example.

It will be clear that a great advantage of our invention is that theuser may keep his eye continually on the object and need not look at theindicating scale in order to bring the desired groove into operationbecause he can not only hear the click of the nose engaging the severalgrooves but he can feel the spring resistance as the nose passes fromgroove to groove. Moreover if the user forgets what the elevation of thesight actually is, he can, without taking his eye from the object, turnmember E until one of the shoulders e or c is engaged and then rotateuntil the desired groove is engaged by the nose f knowing that whenshoulder a is engaged the sight d is in its lowest position and whenshoulder e is engaged the sight is in its highest position.

A great advantage of our invention consists in mounting on the same basethe member E and the body portion of the sight member which in the formshown is frame D.

Another advantage is that our rotary member E is very convenientlylocated near the user and spaced very considerably from the turn buttonsof the worm b and of the slide D.

WVhat we claim is:

1. A sight for firearms comprising a sight member; a rotary member; alever to transmit motion from the rotary member to the sight member tochange the elevation of the sight; and means for supporting said partsin operative relationship.

2. A sight for firearms comprising a springpressed pivotally mountedsight member; a rotary member; a member inter mediate the sight memberand rotary member to transmit motion from the latter to the former tochange the elevation of the sight; and means for supporting said partsin operative relationship.

3. A sight for firearms comprising a spring-pressed sight member; arotary member; a lever to transmit motion from the, ro-,

tary member to the sight member to change the elevation of the sightmember; and means for supporting said parts in operative relationship.

4. A sight for firearms comprising a sight member; a rotary memberhaving its axis crosswise of the firearm and having an operativeperiphery at progressively increasing distances from said axis; and alever, one portion of which engages the sight member and another portionof which engages said periphery, the lever being pivoted between saidportions and transmitting motion from the rotary member to the sightmember; and means for supporting said parts in operative relationship.

5. A sight for firearms comprising a movable base; a shaft mounted onsaid base-extending crosswise of the firearm; a sight member pivoted onsaid shaft; a spring Copies of this patent may be obtained for pressingsaid sight member toward the firearm; a rotary member mounted on saidshaft and having an operative periphery at progressively increasingdistances from its axis; and a lever pivoted on said base, one end ofwhich lever engages the sight member and the other end of which engagessaid periphery to transmit motion from the rotary member to the sightmember, said base supporting said other parts in operative relationship.

6. A sight for firearms comprising a sight member a rotary member havinga plurality of holding ortions and a plurality of corre spondingindicating symbols, each symbol being at the top of said rotary memberwhen its corresponding holding portion is at the bottom of said rotarymember; and a member intermediate of the sight member and rotary memberto transmit motion from the latter to the former, said intermediatemember engaging the desired one of said holding portions and alsoengaging said sight member to change the elevation of the latter; andmeans for supporting said parts in operative relationship.

7 A sight for firearms comprising a shaft extending crosswise of thefirearm; a sight member pivoted on said shaft; a rotary member mountedon said shaft and having an operative periphery at progressivelyincreasing distances from its axis; a lever to transmit motion from saidrotary member to said-sight member to change the elevation of thelatter; and means for supporting said parts in operative relationship.

8. A sight for firearms comprising a sight member; a rotary memberhaving its axis crosswise of the firearm and having a plurality ofgrooves, the inner portions of the grooves being at different distancesfrom said axis; a lever having a nose at one end to engage the desiredone of said grooves and having its other end adapted to engage saidsight member to transmit motion from the rotary member "to the sightmember; and

7 means for supporting said parts in operative relationship.
